CIS OFDM modems logs

this is not the result of a systematic monitoring but just a grouping of my (2015) logs sorted by frequency and waveform; so it doesn't claim to be complete or to provide a sort of schedule for such transmissions. Very poor information about CIS protocols and modems can be found in the web and it is worth noting that in Russia today there is a large replacement of HF equipment and installations: I only know a few links and this is one of these: SDR HF Wireless modem MDM-40K0
About the users... more or less reliable it can be argued that "SERDOLIK" waveforms family is used by the CIS/Russian Diplomatic networks. It should also be understood that a same modem can be used by various agencies, depending on the offered features (such as resistance encryption algorithms and the like): for example, the "old" AT-3004 modem is used by both civilian and military agencies and there are options for the export markets in Latin America and Middle East. Actually, the situation is similar to NATO standards: we log several and same ALE-2G signals but the particular user can be identified only by the callsigns.


notes:
 
- CIS-12 AT-3004D (aka MS5, fire) is not considered as an OFDM waveform and so those logs are not reported here. 

- Frequencies are USB, times in UTC.
